rTo all whom it may concern.'

Be it known that l, HARRY BUBIN, a citi- Zen of the United States,residing at .Philadelphia, in the count).7 of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Winding and Cutting Cloth, of which the following is aspecification.

The principal objects of the present invention are, first, to provide amachine for winding cloth or fabric into a roll and for subsequentlycut-ting the roll into coiled or wound strips of any width and whichshall be strong, durable, reliable and accurate; second, to provideaccurate mechanism for relatively adjusting the roll of cloth or fabricand the cutting knife or cutter in order to easily and quickly cut theroll exactly at any required point or points; third, to provide a speedchanging mechanism for winding at relatively low and easily controlledspeed and for cutting at higher speed; fourth, to provide simple devicesfor quickly changing the cloth drive from the center to the end of theroll; and fifth, to provide for properly grinding the knife or cutter.@ther objects of the invention will appear from the followingdescription, and the invention will be claimed at the end hereof afterhaving been first explained in connection with the accompanyingdrawings, forming part hereof, and in which- Figure 1, is an elevationalview, partly in section, of the front of a machine embodying features ofthe invention.

Figs. 2 and 3, are respectively, elevational views of the left andrighthand ends of the machine. Y

Fig. 4, is a cross-sectional view drawn to an enlarged scale andillustrating means for driving from the center of the roll.

Fig. 5, is a face view of a chuck for driving from the end of the roll,and

Fig. 6, is a schematic sectional view illustrative of the windingoperation.

In the drawings 1 and 2, are standards, as of metal, and they togetherwith the table 3, and the three tie rods 4, 5 and 6, arranged at theapeXes of a triangle, constitute a rigid and strong frame for theworking parts. 7, is a shaft revolubly mounted in bearings, shown as ofthe ball type, in the standard 2, and in an extension 8, of the standard1, which extension is carried by the rods 4, 5 and 6. This shaft 7, iscircumferentially grooved at 9, to provide clearance for the cutter 10,and is longitudinally provided with a greove having inclined walls 11and 12, Fig. 4, for the dual purpose of driving and releasing, through adetachable rod 13a, the paper tube 13, upon which the fabric A, is woundand of acting as a keyway byl which a key, on the slidingV chuck 14, .isdriven from the shaft 7. The chuck 14, is provided with radiallydisposed T-head slots 15, in which slide jaws havinflr radially disposedinturned pins 16, and toothed backs 17 (Fie. l) which coperate withspring'detents 11a, so that as the jaws are pushed inward they areauton'iatically latched, and the jaws can be moved outward by releasingthe spring detents 17a. The portion 18, of the extension 8, can bepulled toward the left in Fig. 1, along the rod 5, thus disengagingdowel pins 19, from the extension 8, and also disengaging the shaft 7,so that the part 18, can be turned down to permit of the removal of workover the end of the shaft 7. 20, is a generally triangular plateslidable on the rods 4 and 6, apertured for the passage of the rod 5,and at its apeX engaging the chuck 14, in such a j way that the latteris free for rotation. The plate or traveler 20, is centrally providedwith a nut 21 engaged by a screw 22, revolubly mounted between thestandards 1 and 2, and turned in either direction by a handwheel 28, atthe front of the machine and near Ythe lefthand end thereof, through theintervention of a hand-wheel shaft24, and bevel gears 25. Loose on theshaft 7, are two driven clutch-members 26 and 27, of which eithercoperates with a third clutch member 28, splined for endwise motion onthe shaft 7, and shifted by a-shipper 29 (Fig. 3), the purpose being toprovide for driving the shaft 7, at two different speeds, oneappropriate for winding and the other appropriate for cutting. To drivethe shaft 7, for winding, use is made of the clutch member 27 driven bya sprocket chain 30, from friction clutch element 31, operated fromVpulley 32, and controlled from pedal 33,'through sliding rod 34,connected with the pedal' and with the friction clutch element 31, sothat by operating the pedal the clutch lelement 31, may be more or lesstightlyheld up to the pulley clutch element 82, and in this way theoperator has control of the rotation of the shaft 7, and may instantlystop such rotation. shaft 7, for cutting, use is made of the To drivethe clutch member 26, driven by a sprocket chain 35', from the hub36,'Afast with the pulley 37, onto which the motor belt 38, is shiftedby the belt shipper 39, operatable from the lefthand end of the machine.The shaft 40, of the cutter 10, is journaled ,in a swinging frameconsisting of two shaft carrying arms 41 and an operatin handle 42, andmounted on the rod 5. r he Vcutter or circular knife 10, is alined withthe notch 9, in the shaft 7, and the movement of the cutter away fromthe shaft is limited by the adjustable stop 43 (Fig. 2) on the inner'face of the standardfl. The cutter and its shaft are driven by thechain and sprocket wheels 44 and 45 (Fig. 3) of which 45, is mounted onthe rod 5, and driven by a sprocket wheel 46, fast to it and in turnVdriven by a sprocket chain and wheel 47,

from the clutch member 26. 4S, is a grinder having its shaft journaledin a. bracket 49,

.carried by the'frame of the machine and driven by a sprocket chain andwheels 59, from a shaft 51, carried by brackets 52a, and driven from atoothed wheel 52, arranged on the hub 36, and meshing with a toothedwheel 53, having sprocket chain and wheel connection 54, Fig. 3, withit, thus the rims of the grinder and of the cutter run in the samedirection at the point of contact, while the rims of the roll of fabricand cutter run in opposite directions at the point of contact. 55, is atension device arranged on the table 3, and consisting of a fixed and aswinging member provided with rods ar ranged out of alinement with eachother.

To wind a fabric into a roll, a paper tube 13, is put over the shaft 7,with a wire or rod 13a, between and in the groove 11-12. For thispurpose the movable part 18, is swung clear of the lefthand end of theshaft 7 The handle 29, is moved to drive the shaft 7, from the clutchelement27, and its accessories at a comparatively low speed, and theshipper 39, is moved to drive the pulley 32, from the motor. The fabricis led under rod 4, over the table 3, through the tension device 55,past the rods 6 and 5, and iswound on the tube 13. The winding operationis controlled by the pedal 33, which can be operated to stop it at anymoment. To cut the wound fabric into strips the wire 13a, is withdrawn,the chuck jams are pushed in so that the pins 16, take into the woundroll of cloth and the belt shipper 39, is moved to apply power to thepulley 37, from which the cutter 10, and grinder 48, are driven, as hasbeen described. The hand wheel 23, is turned to feed the roll to theleft with a positive feed and to accurately position it in respect tothe cutter 10, and for this pur pose reference may be made to the 'gage56, carried by the rod 5. The handle 42, is manipulated to swing thecutter carrying frame and cause the cutter to cut the roll of at lowspeed, a chuck slidable on the shaft Y and splined to said groove andprovided with fingers for driving the tube from the chuck at high speedin the Vabsence of the rod,

means for sliding the chuck and tube on the shaft, and a rotary cutter,substantially as described.

2. In a machine of the type recited the vcombination of a rotatableshaft for fabric,

a rotatable cutter shaft having a sprocket wheel, a grinder shaft havinga sprocket wheel, a driving element having a sprocket wheel and atoothed gear wheel, a fabric shaft driving element having a pair ofsprocket wheels, an intermediate toothed wheel meshing with said toothedgear-wheel, a sprocket chain between the sprocket wheel of the drivingelement and one of the sprocket wheels of the fabric shaft drivingelement, a sprocket gear including a pair of connected sprocket wheels,a sprocket chain from one of the last mentioned wheels to a sprocketwheel of the fabric shaft driving element 'and a sprocket chain from theother of the last mentioned wheels to the sprocket wheel of the cuttershaft, and a sprocket chain from the intermediate tooth wheel to thesprocket wheel of the grinder shaft, substantially as described. Y

In a machine of the type recited the combination of a pair of standards,three parallel rods arranged at the apeXes of a `triangle and connectingsaid standards and of which the bottom two are disposed side by side, anendwise immovable swinging frame mounted on the top rod and providedwith a cutter, a traveler slidable on the horizontally spaced bottomrods and apertured for the passage of the top rod and provided with arotatable clutch, a feed screw turnable on the standards and engaging anut provided on the traveler to shift the latter in respect to thecritter, and a hand wheel for turning the screw, substantiallyY asdescribed.
